Answer:

y = 0.981

Step-by-step explanation:

Given expression:

  • 5.7y-5.2=y/2.5

Solution:

  • 5.7y-5.2=0.4y

Subtract 0.4y from both sides:

  • 5.7y-5.2-0.4y=0.4y-0.4y
  • 5.3y - 5.2 = 0

Add 5.2 to both sides:

  • 5.3y-5.2+5.2 = 0+5.2
  • 5.3y = 5.2

Divide both sides by 5.3:

  • \cfrac{5.3y}{5.3}  =  \cfrac{5.2}{5.3}
  • y = 0.981

Hence, y = 0.981.

5.7y-5.2=y/2.5

Add 5.2 to both sides:

5.7y = y/2.5 + 5.2

y/2.5 = 0.4y

5.7y = 0.4y + 5.2

Subtract 0.4y from both sides:

5.3y = 5.2

Divide both sides by 5.3:

y = 5.2/5.3

y = 0.98113

The Pythagorean theorem is a² + b² = c². Solve for b. b=±c+a−−−−√ b=±c2−a2−−−−−−√ b=±c2+a2−−−−−−√ b=±c−a−−−−√
uysha [10]

a^{2} +b^{2} =c^{2}

As we have to solve for b, it means we have to isolate b

So first of all subtract a^{2} from both sides

So we get

b^{2} =c^{2} -a^{2}

Now we need b , but its b^2 , so we can take square root on both sides.


taking square roots on both sides

b= +- \sqrt{c^2 -a^2}


Hence option B is correct

Answer:  The first option with sss as part of the proof

Step-by-step explanation:

The lengths of the arcs drawn in the constructions are the same, so when the line is drawn, the lengths of the sides will all be the same.  SSS is proof of congruence.

CPCTC is an acronym for "corresponding parts of congruent triangles are congruent."
